An indicator of a failed call setup will trigger the call to be re-originated transparently to an emergency center where live operators can handle the call on a 24hours/day basis. In one embodiment, an emergency center is a call center that is operated by a network provider or a third party provider to support emergency calls when a PSAP cannot be reached by a caller for various reasons. The emergency center is capable forwarding a call to the appropriate PSAP for call termination on behalf of the E911 caller.
